Genomic analysis reveals genetic diversity and selection signatures of the Yantai Black pig during domestication and breeding.

ABSTRACT:

Objective

Yantai Black pig (YT), as a native population of the eastern China's Jiaodong Peninsula of Shandong province, characterized by coarse feeding tolerance, strong disease resistance, early sexual maturity, high litter size, and superior meat quality. However, the genetic characteristics and variations underlying its crucial economic traits remain poorly understood.

Methods

In this study, we resequenced the whole genome of 17 YT individuals from distinctly different lineages breeding in three conservation farms to detect single nucleotide polymorphism (SNP) density, pairwise fixation index (F _ST), nucleotide diversity (π), runs of homozygosity (ROHs).

Results

Our findings revealed that YT has higher genomic diversity compared to Chinese partial
